So if you list with a broker, who offers $1500 or 10% commission, whichever is greater, and that broker works with another brokerage firm, who finds you a buyer, do both brokers get commissions? For example, I list with company A. Company A advertises my unit. Company B knows someone wanting to buy that unit and helps company A negotiate that sale. What is fair for original Company A to pay for a finders fee to Company B? Is it from their pocket or mine?
